WEATHER STRIP FOR INSWINGING CASEMENT Application filed September 11, 1922. VSerial No. 587,529.

My invention provides an extremely simple and highly efficient weather strip for inswinging casements and, generally stated, the invention consists of the novel construction, arrangement and combinations of parts hereinafter described and defined' in the claim.

Particularly, the invention provides a new and improved form of metallic sill strip for co-operation with a supplemental strip carried by the under edge of the casement. Preferably, the sill strip is of brass and of trough-like form, provided with upstanding inner and outer stop flanges, the latter of which projects above the former and, at its upper edge, has a horizontal extension that projects inward or toward the inside stop flange. Preferably also, the supplemental strip is of copper, bent approximately U- shaped in cross-section and adapted for close engagement with the horizontal extension of the outer stop fiange of the sill strip.

In the accompanying drawings, which illustrate the invention in its preferred form, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a fragmentary vertical section taken through the lower portions of a winclow frame and casement and. showing the improved weather strip applied thereto; and

Fig. 2 is a perspective showing portions of the sill strip and supplemental strip removed from working position.

The numeral 3 indicates a window frame v comprising a sill 4 and stool 5, and the nu-V meral 6 indicates an inswinging casenent or window sash, which willbe mounted at one edge on vertical hinges, in the custom-dry rflhe sill strip 7 comprises a flat base plate with upstanding inside and outside stop flanges 8 and 9, the latter having a horizontal extension 10 that projects toward the stop flange 8 in a plane above the upper edge of the latter and terminates short of the vertical plane of said fiange 8. The base plate of this sill strip is shown as provided with depending sharp-edged ribs 11 that will be pressed down into the wooden sill 4. Preferably, the base plate of the sill strip projects outward of the channel or trough-likecbody portion of said strip, so as to completely cover the horizontal upper portion of the sill. Screws 12 serve to tightly clamp the sill strip onto the sill,

upper flange projecting considerably outward of its lower fiange, and this upper flange, by

nails or' brads 15, is secured to the under edge of the casement 6. Preferably, the casement 6 is rabbeted at 16 to receive the supplemental strip 14, and inward of said rabbet 16the under edge of the c asement is formed with a lower rabbet 17 that forms a close joint with the inside stop flange 8, when the casement is closed. Preferably, and as Shown, the component parts of the sill strip are formed integral and by a process known as extruding of metal while in semi-fluid or plastic condition.

vWhen the casement is closed, a perfectly water-tight joint is made between the window sill and casement. In the first place, a very close joint is made between the hooklike or hook-acting supplemental strip and the horizontal flange extension of the sill strip, but if any water should be dashed inward between these, it will be caught in the trough of the sill strip and would run out through the drain passages 13. The close joint above made and the second close joint made between the inside stop flange 8 and the rabbet 17 of the casement, prevent leakage of air either inward or outward. It may be further noted that any water that might leak or pass beween the supplemental strip and the horizontal fiange extension of the sill strip will be directed downward against the outer-.stop flange 9 and will immediately run out through the drain passages 13 so that vthere is no possibility of the water being dashed over the inside stop flange 8. These features above noted produce a very highly efficient, yet extremely simple, weather strip for the lower portions of casements. So far as this invention is concerned, any suitable weather strips may be applied to the vertical edges and top of the casement and window frame, or they may be omitted when desired.

vWhat I claim is:

The combination with a window lframe and a swinging casement, the former having a sili and a stool extending above said sili, of a one-piece netailic sili strip secured to the sili and a suppiementai joint strip secured to the inner edge of said casenent, said siil strip having upstanding inner and outer flanges, the former of Which engages the outer edge of the stool andV projects there'- above, said outer flange being located materialiy inward of the outer edge of the sili strip and the outer face of the casernent and having a horizontai inWard extension lying in a plane above the upper edge of the inner fiange with its inner edge spaced materially [5 outward thereof, screws securing the sili strip to the sili and extending through hoies in said sili strip, certain of which are between the inner flange and the inner edge of said extension on the outer fiange, the under edge of the casenent having inner and outer rabbets, the former of Which overiaps the inner fiange and the latter of Which overlaps the inner edge of said extension on the outer fiange, said supplenentai joint strip being U-shaped in cross section and arranged to engage said extension of the outer flange, and a drain hoie in the outer fiange.

In testimony Whereof I aflix my signature.
